Stop Downloading Before Out Of Disk

Today, Dropbox does not gracefully handle running out of disk. It keeps going until it gets an error from the operating system that there's not enough space left at which point it's not even able to show you how much space it's using because there's not enough disk space for that to function. Ideally Dropbox would leave at least a couple GB so the system can keep functioning until the user has time to do something about it. Also, don't keep retrying - one notification after another about not being able to download is useless until a significant amount of space has been freed up one way or another. Making it easy to open a window with space usage and encouraging the user to keep more files cloud only would be much more user friendly.
